Back in 2009 I decided to research and write a speech called "Economic Crisis Explained in 7 minutes"
Bett Correa explains the Economic Crisis in 7 minutes by reviewing the necessary items needed for a Bubble. Why did the mortgage crisis occur?
Sources for this speech come from Dumb Money by Daniel Gross, Wired Magazine's The Secret Formula that Destroyed Wall street, 3 years of Economist Magazines, and This American Life's special coverage of the financial crisis.
